""crockadiles are desedants and havent changed so smaller but still dino's"
No, they're not. True, they are essentially the same as they were previously but that doesn't make them dinosaurs.
"I think in the vastness of the oceans their could still be dino we havent seen yet still living"
Possibly. I wouldn't count on it, but it's certainly possible.
""Based on what I have learned (history class even history channel) plus the Word's teaching, I honestly believe GOD destroyed the dinosaurs (or giant creatures) in the Flood, if not maybe a meteor/comet."
So, your god did it but--if by some amazing chance he didn't (no shit!)--then you'll accept the currently accepted idea of how the dinosaurs met their end. Strange that one would prefer mythology to reality like that.
"I think this was for our own sake since the Fall, we cursed the earth basically and lost control over Creation."
By eating a fucking apple that your god, omniscient as he was, placed in the Garden to begin with while knowing full well that the Serpent (who god, being omnipotent, allowed into the garden) would tempt Eve into eating the damned thing. How does that story not strike everyone as being completely and utterly absurd in ever single fucking way imaginable? Don't you people actually process information when it's given to you or do you just accept it because your preacher says it or the Bible contains it?
"If the dinosaurs were indeed real, they would have destroyed us fast."
Not all dinosaurs looked like a T-Rex you know. The majority would have probably been no more dangerous than anything else our predecessors had to deal with.
"I believe dinosaurs were on Noah's Ark."
Oh good god. Fine. Believe it. Now show me how Noah's Ark could have been constructed, stayed sea worthy, been crewed by eight people for such an extended length of time or contained such creatures. Go ahead. I'll wait.
"Then, after the flood was over, all of the plants, animals and people that wasn't on the Ark were drowned."
Odd that the geologists don't find any evidence of such an event.
"Dinosaurs were really big, therefore they needed more oxygen to breath, than humans and littler animals. All of those plants that were destroyed by the flood gave off oxygen. So in conclusion, the dinosaurs died off because of lack of oxygen that was needed for them to live."
I think you're not getting enough oxygen.
"it seems to me that when the canopy of water over the earth was pierced and fell on the earth, the climate was so much cooler after the flood, that the dinosaurs could not survive and became extinct."
You moron. There was not, nor could there ever have been a "water canopy." I hope whichever creationist fuckwit came up with such a monumentally stupid idea has a special level of hell all his own awaiting him after death.
